Some of the Pmods, such as the PmodOLED and the PmodCLP, need a higher operating voltage to run their screen than is normally supplied by system boards. This predicament could be solved by using an external power supply to power the screens, but that can get pretty inconvenient especially if you want your project to be portable. A slightly easier method that does not require a power supply is a boost converter circuit.
Digilent hasn’t always been located at 1300 NE Henley Court! Looking back at its old locations is so fun — getting to see where we were and how we’ve grown. Today, we’d like to show you one of our former locations, the one right before our current building. This was Digilent’s fourth location. Norm snapped these pictures on a Friday night in 2006, just after we had re-organized the main floor. This was the “combine” building — it sits above what is now one of Pullman’s fine dining establishments, Black Cypress.
With any upcoming projects you may be doing, will you be using transistors? A few months ago, Brandon wrote a post detailing the basics of transistors — what they are, how they work, how they can be used, etc.
Robots that run around on motors are pretty sweet. These motors traditionally tend to be DC motors that are controlled through the use of an H-Bridge, which can change the flow of current so that the motor is able to run forwards or backwards. H-bridge modules, such as Digilent’s PmodHB3 or PmodHB5, also tend to have two pins labeled as Sensor A and Sensor B that measure which direction the motor is rotating. The two sensors, A and B, will be wired to the outputs of components known as Hall effect sensors. Unsurprisingly, these measure the Hall effect. But rather than having the “word in the definition” problem, let’s learn some of the practical details.
As February, Black History month, draws to a close, we want to highlight the achievements of an amazing and inspiring engineer. Astronaut Robert Lee Curbeam, Jr., was born in 1952 and is the astronaut who holds the record for most space walks on a single flight.
The binary search tree (BST) is a data structure that is much different from the other structures that we’ve gone over so far. Unlike stacks, queues, and lists, a BST’s struct is not a “straight-line”. Each node in a BST has a left and right child node.
Recently I released a collection of projects going over how to use LAbVIEW, the chipKIT Max32, and the PmodACL to do some neat stuff with accelerometer data. These include filtering, multidimensional vector plots, and tilt measurement.
Recently, we found some great snapshots into what life was like at Digilent between 2003 and 2005. How things have changed in the ten years or so since most of these images were taken!
MPIDE comes with a nice serial monitor where you are able to print out values that your system board has measured onto your computer screen. But if you are able to print things onto your computer screen, wouldn’t it make sense if the chipKIT board also accepted and processed values that we typed into the serial monitor? It would make a lot of sense, which is probably why we can do just that. Let’s find out how.
Recently, a user of our products posted a tutorial about using a chipKIT uC32 to remotely control an FM Radio. We always love to see our users creating cool projects and try to give space here not only to projects created by us at Digilent but also by you the user. This project does require the use of multiple components and could be a bit overwhelming to a beginner, but we encourage you to try it out if you so choose!
Recently, one of our hardworking interns started a new video series. You may have seen James’ blog series about Pmods. Now there’s a video component as well! James begins the series by introducing Pmods and talking about their history.
One of our lesser known products that definitely deserves some more attention is the Electronics ExplorerTM Board. This is an incredible piece of hardware that everyone interested in electronics should have. When I first started in electronics, I used the popular Analog Discovery. After using the EE Board, another analog design product offered by Digilent, it has become my new favorite.
